    Cost allocation in the establishment of a collaborative transportation agreement - an application in the furniture industry
    (Basingstoke Basingstoke Stockton Palgrave, 2010-05-26) Audy, Jean-François.; D'Amours, Sophie; Rousseau, Louis-Martin
    Transportation is an important part of the Canadian furniture industry supply chain. Even though there are often several manufacturers shipping in the same market region, coordination between two or more manufacturers is rare. Recently, important potential cost savings and delivery time reduction have been identified through transportation collaboration. In this paper we propose and test on a case study involving four furniture companies, a logistics scenario that allows transportation collaboration. Moreover, we address the key issue of cost savings sharing, especially when heterogeneous requirements by each collaborating company impact the cost-savings. To do so, we propose a new cost allocation method that is validated through a case study. Sensibility analysis and details about the actual outcome of the case study complete the discussion.

    An empirical study on coalition formation and cost/savings allocation
    (2011-09-16) Rönnqvist, Mikael; Audy, Jean-François.; D'Amours, Sophie
    Interest has been raised by the recent identification of potential savings through collaborative planning in logistics operations. Even though substantial savings can be realized, two key questions exist: (i) how should potential savings be divided among a group of collaborating companies and (ii) among potential collaborating companies, how should collaborating group(s) be formed? These two questions are studied in a specific context: among potential collaborating companies; a subset, denoted the leading companies, performs collaborative planning on behalf of the others and together, they initiate formation of a collaborating group. We use the concept of a business model to detail such context. Based on the literature on network formation where potential savings are modelled by a cooperative game, four business models are explored in four different subsets of leading companies. We propose a network model as a method to determine the stable collaborating group in each computation. A case study including eight forest companies is described and analyzed. Results show that very different solution characteristics can be achieved depending on the business model selected.

    An educational game with dragons’ den experiences for supply chain management training
    (INFORMS, 2020-03-30) Feng, Yan; Rönnqvist, Mikael; Audy, Jean-François.; D'Amours, Sophie
    This article presents an educational game to engage university and industrial stakeholders in collaborative training for supply chain management courses. The game will help students learn complex supply chain management issues. There are two integrated parts: a case ethod through an industrial case and an activity-based game featuring role plays based on international television shows such as Dragons’ Den in Canada or Shark Tank in the United States. We developed a game framework to illustrate how the game can be prepared and played in classrooms. Although the game is primarily developed for classroom teaching, it may be adapted to other training environments. We have provided two examples to demonstrate how the game can be played as a short game in conference environments. Game experiences and feedback are presented with comments from various game participants. By interacting with stakeholders and tackling a real-world business case, students can better understand stakeholders’ business goals, the importance of supply chain collaboration, and the impacts on supply chain decisions.

    A framework for an efficient implementation of logistics collaborations
    (Oxford Blackwell, 2010-12-07) Rönnqvist, Mikael; Lehoux, Nadia; Audy, Jean-François.; D'Amours, Sophie
    In order to beat the competition, access new markets, and respect operational, social, and environmental constraints, enterprises establish collaborations with many other business entities. Furthermore, with costs and information sharing, organizations have the opportunity to optimize their logistics activities. However, each enterprise has its own objectives and typically makes its own planning decisions to meet these objectives. Therefore, it becomes crucial to determine how business entities will work together as well as the value of the collaboration. Specifically, it is necessary to identify how logistics activities will be planned and executed, who will take the leadership of the collaboration, and how benefits will be shared. In this article, we explain how to efficiently build and manage inter-firm relationships. Moreover, we propose five coordination mechanisms that contribute to ensure information sharing, the coordination of logistics activities, and the sharing of benefits. Case studies are used to demonstrate the utility of the framework.

    Inter-firm collaboration in transportation
    (2013) Audy, Jean-François.; Rousseau, Louis-Martin; D'Amours, Sophie
    Dans la littérature académique et professionnelle relative au transport de marchandise, il y a longtemps que les méthodes de planification avancées ont été identifiées comme un moyen de dégager des économies grâce à une efficacité accrue des opérations de transport. Plus récemment, la collaboration interentreprises dans la planification du transport a été étudiée comme une source de gain supplémentaire en efficacité et, par conséquent, une opportunité pour dégager de nouvelles économies pour les collaborateurs. Cependant, la mise en œuvre d'une collaboration interentreprises en transports soulève un certain nombre d'enjeux. Cette thèse aborde trois thèmes centraux de la collaboration interentreprises et démontre les contributions via des études de cas dans l'industrie forestière et du meuble. Premièrement, les moyens technologiques pour soutenir une collaboration en planification du transport sont étudiés. Un système d'aide à la décision supportant la collaboration en transport forestier est présenté. Deuxièmement, le partage entre les collaborateurs du coût commun en transport est étudié. Une méthode de répartition du coût de transport tenant compte de l'impact - l'augmentation du coût de transport - des exigences inégales entre des collaborateurs est proposée. Troisièmement, la création de groupes collaboratifs - des coalitions - dans un ensemble de collaborateurs potentiel est étudiée. Un modèle réseau pour la formation d'une coalition selon les intérêts d'un sous-ensemble de collaborateurs adoptant ou pas un comportement opportuniste est détaillé. De plus, pour soutenir l'étude des thèmes précédents, la thèse comprend deux revues de la littérature. Premièrement, une revue sur les méthodes de planification et les systèmes d'aide à la décision en transport forestier est présenté. Deuxièmement, à travers la proposition d'un cadre pour créer et gérer une collaboration en transport et, plus généralement en logistique, une revue de travaux sur le transport et la logistique collaborative est offerte.

    Planning systems, agility and customisation in wood supply chains – results from six international case studies
    (2013-07-01) Rönnqvist, Mikael; Moreira, Matheus; Audy, Jean-François.; Westlund, Karin; D'Amours, Sophie; LeBel, Luc
    This paper is based on wood supply chain (WSC) data collected in six countries (Canada, Chile, France, Poland, Sweden, and USA) where a total of 94 local actors and experts were consulted. For each WSC studied, processes for operational plan-ning and execution of the procurement activities were mapped. Descriptions of the information, material and financial flows were also completed. Three basic designs of planning systems were identified, and for each design, a decision matrix was de-vised. WSC agility capabilities were assessed according to a four dimensions refer-ence model and compared with those theoretically required by the environment's uncertainties. When comparing location of the decoupling point, agility capabilities, and average order fulfilment cycle time of each WSC, it was possible to reinforce results found in the literature which state that supply chain agility is linked to shorter order fulfilment cycle time. Finally, the personalisation capabilities of each WSC were assessed and two key processes were identified where most of the product differen-tiation activities along a WSC occur.

    Issues and experiences in logistics collaboration
    (Springer, 2009) Rönnqvist, Mikael; Lehoux, Nadia; Audy, Jean-François.; D'Amours, Sophie
    Collaborative logistics is becoming more important in today’s industry. This is driven by increased environmental concerns, improved efficiency through collaborative planning supporting resources sharing and new business models implementation. This paper explores collaborative logistics and reports on business applications within the forest products industry in Sweden and Canada. It first describes current opportunities in collaborative planning. It then discusses issues related to building the coalition as well as sharing resources and benefits. Three business cases are described and used to support the discussion around these main issues. Finally, different challenges are detailed, opening new paths for researchers in the field.

    Alternative logistics concepts fitting different wood supply situations and markets
    (Centre interuniversitaire de recherche sur les réseaux d'entreprise la logistique et le transport, 2012-06-01) Rönnqvist, Mikael; Pinotti Moreira, Matheus; Audy, Jean-François.; Westlund, Karin; D'Amours, Sophie; LeBel, Luc
    In this research project, we developed a framework for describing different wood supply chains (WSC) in a generic way and assessing their agility and tailoring capabilities. The studied WSC comprises the planning and execution, at the operational level, of all activities, from selling agreements to delivery of forest products at the mill yard. required by the environment’s uncertainties are compared and discussed. Finally, tailoring capabilities were assessed, based on the location of the decoupling points and their respective order fulfilment cycle time. Two processes were identified, where most of the product differentiation activities along a WSC occur: harvesting with the CTL method and merchandising at a roadside landing using the FT method. The capabilities to tailor product specifications are superior before rather than after one of these processes. Moreover, a typology of assortments according to the level of tailoring is provided and the financial incentive to produce a basket of assortments with a higher level of tailoring is discussed. Finally, when comparing the location of the decoupling point, the agility capabilities and the average order fulfilment cycle time, it was possible to reinforce the results from the literature, which state that supply chain agility is linked to shorter leadtime. The framework is useful to organisations interested in describing their WSC and assessing their agility and tailoring capabilities. By assessing the tailoring and agility capabilities of a WSC, the framework can support an organisation in an exercise of selfdiagnosis that leads to the identification of improvement opportunities to work on. Moreover, by assessing different scenarios for its WSC (e.g. the introduction of new technology, the addition of a new value proposition for a customer), an organisation can anticipate the impacts of changes. Finally, the framework introduced a common vocabulary to be used by researchers and practitioners in different disciplines (e.g. forest engineering, management sciences, industrial engineering). It represents an original attempt to develop a reference model for future research addressing WSCs. These include the purchase or selection of harvesting blocks, harvesting scheduling and execution, as well as transportation scheduling and execution. The framework includes a set of descriptive templates including e.g. a description of the actors, their planning and execution processes, the decoupling points used, together with information, material and financial flows. The proposed framework was applied to case studies in six countries (Canada, Chile, France, Poland, Sweden and USA) where fieldwork allowed us to collect information from 94 local actors and experts. The case studies allowed a list of options (i.e. catalogues) to be generated for different descriptive elements within the framework. We generated catalogues of 16 types of actors involved in a WSC, seven locations of decoupling points, four types of value commitment processes, eight standing timber and harvest timber pricing mechanisms and several payment methods for standing timber, harvested timber, harvesting and primary and secondary transportation. We also developed 17 generic processes for any planning and execution activities within a WSC, as well as 13 generic planning decisions at the operational level. Three basic designs of planning systems were identified: 1) integrated sourcing and harvesting planning, 2) integrated harvesting and transportation planning, and 3) decoupled sourcing, harvesting and transportation planning. We also identified six logistics techniques to adjust supply to demand. The agility capabilities of the WSC were assessed in four dimensions: customer sensitivity, process integration, information drivers and network integration. The developed methodology used a 0-4 scale to rate how well different enablers and practices, identified along the main processes within a WSC, contributed to each of these four dimensions. A WSC should strive towards proper agility capabilities in response to uncertainty in their environment. The agility capabilities evaluated in the case studies and those theoretically

    Business models for collaborative planning in transportation : an application to wood products
    (Springer, 2007-01-01) Rönnqvist, Mikael; Audy, Jean-François.; D'Amours, Sophie
    Transportation is an important part of the wood fibre flow chain in forestry. There are often several forest companies operating in the same region and coordination between two or more companies is however rare. Latelv, the interest in collaborative transportation planning to support co-ordination has risen since important potential savings have been identified. Even though substantial savings can be realized, it seems that companies' willingness to collaborate is tightly linked to a business model driven by one or many leaders. In this paper, we study a specific business model where one company leads the development of the coalition. The impact of different behaviours of the leading company (i.e. altruistic, opportunistic) is illustrated using an industrial case study of eight forest companies.
